When a date is set as a report parameter in the HTML5 viewer, it formats the parameter as a JSON date using a timezone. Where no time is specified this results in a time part added to the date when received at the server. This is a problem, especially for browser in a negative offset zone, e.g. US, where upon the date goes to the previous day. Please add support for parameter types of date, where no time is present and no conversion is done anywhere.
